I've got an iomega zip drive (100 mb) that I recently bought. Everythings was working fine until today when i tried to back up some files to a zip disk. I got an error message asking me to put a disk into F drive. The problem is there was already a disk in there. I retried it, same message. I tried using another disk and got a message saying the disk wasn't fromatted. There wasn't anything important on it so I tried to format it. So then i get an error message at the end telling me it can't format the disk. What is going on? This sort of thing makes my fuse real short if you know what i mean. i don't think it's too much to ask for a new product to work!!!!!!
